SOFA-BED.

SPECIFICATION forming part of Letters Patent No. 453,474, dated J une 2, 1891.

Application filed December l5, 1890. Serial No. 374,681. (No model.)

To @ZZ whom it may concern.-

Be it known that we, `Vieron A. HALL- Qvisr and GUsTAF E. WENNBERG, both citizens of Sweden, and residents of Boston, in the county of Suolk and State of Massachusetts, have jointly invented new and useful Improvements in Sofa-Beds, of which the following, taken in connection with the accompanying drawings, .is a specification.

This invention relates to improvements in sofa-beds, and it is carried out as follows, reference being had to the accompanying drawings, whereinv Figure l represents a front yperspective view of the invention shown in use as a sofa. Fig. 2 represents a plan view of the same shown in position as a bed. Fig. 3 represents a cross-section of Fig. 2. Fig. 4 represents a detail sectional view of a part of the bedframe and one of its hinged sides and the brace for holding vsaid parts in their relative positions when the device is used as abcd. Fig.V 5 represents a transverse section of the framework, and showing in dotted lines the seat' folded together when used as a sofa. Fig. 6 represents a similar transverse section, showing in dotted lines the seat turned over and expanded when used as a bed; and Fig. 7 represents a cross-section on the line X X, shown in Fig. 2.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

The sofa-frame is composed of a back board A and ends B B, which are secured together in a suitable manner.

C is a brace connecting the lower front corners of the ends B B.

BV B are arm-rests7 as usual, preferably secured to the ends B B, as shown in the drawings.

D is the hollow or skeleton seat-frame, provided at each of its two opposite ends with three rigidly-attached trunnions or pins, or pins provided with rolls d, d and d, adapted to be guided in grooves on the interior of the ends B B. Each of such ends B has for this purpose a Semicircular (or nearly so) groove b,

. having anopen mouth h at its front upper zontal groove h. In a line with the horizontal groove b isa horizontalgroove bhaving upwardly-curved or segmental throats or openings b4 and b5 at its respective rear and forward ends, as shown in said Figs. 5 and 6.

Vhen the device is used as a sofa, the seatframe is in position as shownin Fig. 5, in which position the pin d is resting in the rear portion of the horizontal groove b", the pin d is resting in the rear end of the groove b3, and the pin c is resting in the middle part of the said groove h3, or nearly so, as shown in Fig. 5.

When it is desired to use the device as a bed, the seat-frame D is drawn forward until the pin d enters the rearV upper end of the curved groove b and the pin f enters the throat b5, when the seat-frame D may be swung half a revolution on the pin d', resting in the groove b3 in the direction of the arrow shown in Fig. 5, causing the pin d to be guided through the semicircular groove b to its front open end or mouth b', and causing the pin d to be moved out of the throat b54 and to enter the throat h4, after which the bedframe D is drawn forward to the position shown in Figs. 2, 3, and 5, leaving the pin d about midway in the groove b3, the pin d in the forward end of said groove, and the pin d in front of and entirely outside of the mouth of the groove b, as fully shown in Fig. 6.

To the under sides of the seat-frame D are pivoted at e e the bed leaves or extensions E E, having secured to their outer edges the wire or canvas mattress F, as shown in Figs. 2, 3, 4, and 6.

f f f are suitable coiled springs interposed between the seat-frame D and mattress F, as shown in Figs. 2, 3, and 4.

E E are suitable legs or supports, preferably pivoted to the outside of thev hinged leaves E E, which legs serve as firm supports for the'leaves E E when the latter are swung outward and the device used as a bed, as shown in Figs. 2, 3, 4, and 6. For the purpose of holding the leaves E E in the expanded position shown in Figs. 2, 3, 4, and 6, and also for the purpose of properly stretching and holding the mattress F in position while the device is used as a bed, we pivot to each end of the leaves E a preferably curved metal IOO rod G, (shown in detail in Fig. 4,) which is guided in a perforated bracket or lockingpiece g, secured in a suitable manner to the end piece D of the seat-frame D. The rod G has near its upper end a locking projection G, adapted to be held against the bracket f/ by the iniiuence of a yielding spring G when the leaf E is swung outward and the mattress F expanded, as shown in Fig. l.

YVhen it is desired to close the bed, the 'spring if on the rod G is compressed, by which the projection G is released from contact with the outside of the bracket g, thus permitting the rod G to pass freely through the sa-id perforated bracket as the leaf E is being closed, and after being closed it may be locked in position to the seat-frame D by means of hooks 7L or other suitable or equivalent loeking device.

In connection with this our improved sofabed we prefer to use a folding pillow-support at one end of the bed, as is shown in Figs. 2 and Said pillow-support consists of a metal frame K of suitable length and width, the lower part of which is pivoted, preferably, to brackets D D, secured to one of the ends D of the seat-frame D, and in said brackets the said pillow-support K is also longitudinally adjustable. To one end of said pillowsupporting frame K is pivoted a similar frame k, which when in use is swung to the position shown in Figs. 2 and 3. Vhen not in use, the frame 7e `is folded over the frame K and the latter moved in its brackets until it may be folded on top of the mattress F.

To change the bed into a sofa it is only necessary to swing the sides E E upward against the ends D' D and to lock them in such positions. The seat-frame D is then pushed inward suiiiciently to cause the pin d to enter the mouth b of the groove b and the pin d to enter the throat D, after which the frame D is swung half a revolution on the pin d as a pivot in the direction of arrow shown in Fig. G, causing the pin d to enter the groove b and the pin t to enter the throat U and the forward end of the groove b3, after which the frame D is pushed backward to the position shown in Fig. 5. A is the baek-su1i port of the sofa, as usual.

Ilaving thus fully described the nature, construction, and operation of our invention, we wish to secure by Letters Patent and claiml. In a sofa-bed, the endwframes B, each provided with a semieircular groove Z), terminating at one end in an open mouth h andat the opposite end in a horizontal groove b, and a horizontal groove b, arranged above the semicircular groove and provided at its opposite ends with the segmental grooves 71'* b5, in combination with the reversible seat-frame provided with three rigidly-attached trunnions (t d d, one of which is arranged to travel in the semicircular groove and its horizontal end portion, and the other two arranged to travel in the horizontal groove having the segmental end grooves for the purpose of rneversing the seat-frame and extending it 1n front of the end frames, substantially as described.

2. In a sofa-bed, the combination, with the grooved end frames B, of the reversible and extensible seat-frame D, having trunnions engagin g the grooves ofthe end frames, and pro vided at its inner and outer longitudinal edges with hinged leaves E, a spring-mattress F, attached to said leaves, and braces G, provided with locking devices for holding the leaves expanded and stretching the wire mattress, substantially as described.

In a sofa-bed, the combination, with the grooved end frames B, of the reversible and extensible seat-frame D,having trunnions engaging the ends ot' the end frames and provided at its inner and outer longitudinal edges with hinged leaves E, the wire mattress F, attached to said hinged leaves, the braces G, having locking-springs for holding the hinged leaves expanded and stretching the wire mat tress, and legs E', hinged to the leaves for supporting the latter in their expanded position, substantially as described.

4. Ina sofa-bed, the combination, with the seat-frames, of a longitudinally-sliding pil low-frame K, having a movable pivoted connection with one end of the seat-frame, and the supplemental pillow-supporting frame 7u, pivoted to one end of the longitudinally-sliding pillow-frame, substantially as described.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, on this 28th day of November, A. D. 1890.
